AUGUST LICHTFUSS, OF OSHKOSH, WISCONSIN.

DRAWBRInoE-GATE.

To all whom, t may concern.'

Be it known that I, AUGUST Lrcirrross, a citizen of the United States,residing at Oshkosh, in the county of lVinnebago and State of Wisconsin,have invented certain new and useful Improvements in Drawbridge-Grates;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to drawbridge gates and has for an object toprovide a gate carrying a light thereon with improved means fordisplaying the light when the bridge is closed and obscuring the lightwhen the gate is open.

A further object of the invention is to provide a drawbridge gate havingboxes mounted thereon with covers carried by the boxes and lights in theboxes and with improved means for opening and closing the covers as thegate is closed and opened.

With these and other objects in view the invention comprises certainnovel constructions, combinations and arrangement of parts as will behereinafter more fully described and claimed.

In the drawings: Figure 1 is a view of the improved gate open. Fig. 2 isa view of the improved gate closed with the light boxes open displayingthe lights. Fig. 3 is a detail top plan view.

Like characters of reference indicate corresponding parts throughout theseveral views.

The improved gate which forms the subject matter of this applicationcomprises a pair of upright frames 10 and 11 having journal boxes 12land 13 upon their tops respectively, such journal boxes respectivelyjournaling shafts 111 and 15. The shafts 14 and 15 are provided withsprockets 16 and 17 over which sprocket chains 18 and 19 operate to movethe shafts 14 and 15 within their boxes. The shafts 111 and 15 carryrespectively gate bars F20 and 21 provided preferably withcounterweights 22 and 23 to assist in opening and closing the same. Thearms 20 and 21 are carried rigidly upon the shafts 1a and 15 and areopened and closed by the rotary movement of such shafts in their boxes.Adjacent the sprock- Specication of Letters Patent.

Serial No. 701,363.

ets 16 and 17 disks 24. are located, held against movement in anyapproved manner, as by the bars 25 extending from uprights 2G and 27.The disks 24 are provided with eyes 28 into which cables 29 and 30 aresecured, said cables running respectively along the arms 20 and 21 andthrough guides 31 and 32.

Upon the arms 20 and 21 boxes 33 and 34 are mounted having covers 35 and36 hinged thereon and held normally closed by springs 37 and 38. Thecables 29 and 30 connect with the covers 35 and 36 so that when the armsare turned downwardly to closed position as shown at Fig. 2, the disks24. take up enough of said cables 29 and 30 to cause the covers 35 and3G to open against the tension of the springs 37 and 38. Within theboxes 33 and 34 lights 39 and 40 are located, connected in circuit witha source of electrical energy shown conventionally at 41, so that saidlights are lighted within said boxes 33 and 311 but are obscured whenthe arms are open, as shown at Fig. 1, by the closing of the cover butare visible when the gates are closed as at Fig. 2 when the covers areopen.

It will be apparent therefore that when the gates are open as at Fig. .1the covers of the light boxes are closed and no lights are visible. Whenhowever through the medium of the sprocket chains 18 and 19 and theanchoring of the end of the cables 29 and 30 t-he covers of the lightboxes are swung open as the arms descend so that when the arms reachclosed position the interior of the box and the light contained thereinis fully revealed.

I claim 1. A drawbridge gate comprising a fixed disk, a shaft rotatingin the disk, an arm carried by the shaft, means to rotate the shaft, abox carried by the arm, a cover hinged to the box, and a cable havingone end wound about the disk and its opposite end secured to the coverof the box.

9.. A drawbridge gate comprising a fixed disk, a shaft rot-ating in thedisk, an arm carried by the shaft, a light box carried by the arm, acover carried by the box, a lcable having one end wound about the diskand its opposite end secured to the cover, and means to rotate the shaftand move the arm.

3. A drawbridge gate comprising a fixed l Copies of this patent may beobtained for ve cents each, by addressing the Commissioner disk, a shaftrotating eoncentrioally of the In testimony whereof I affix mysigna-ture disk, an arm Carried by the shaft, a, light in presence oftwo Witnesses.
